The invention relates to a hair waving apparatus.

An object of the present invention is to provide for use in connection with Croquignole hair 5, waving clamps a protector designed to take the place of the felt of ordinary hair waving clamps and adapted to permit the strands of hair to be pulled up through its center in such a manner as to be held compactly in a perpendicular line with relation to the scalp and thus permit the ow of air around the hair strand underneath the Croquignole hair waving clamp and the heating element thereof for cooling the head and protecting the scalp.

A further object of the invention is to provide a protector adapted Vto receive air from scalp cooling tubes and to be arranged on the head of a person beneath hair waving clamps soas to allow air to pass over the scalp beneath the clamps and having ports at the sides for `supplying air to the spaces between the clamps whereby the scalp of a person is cooled and protected both beneath the hair waving clamps and at the sides thereof. The protector confines the fiow of air around the hair strand and over the scalp directly beneath the clamps and heating elements thereof and at the same time allows a substantial amount of air to pass out at `the sides of the protector in escaping therefrom as a result of the circulation of air produced by currents of air continuously supplied by the scalp cooling tubes which discharge air into the protector at each end thereof.

A further object of the invention is to provide strong and durable flexible metallic tubing in the air cooling tubes insulated exteriorly for conveying air from a blo-wer to the protectors, which tubes will be adapted to permit a maximum amount of ilexibility and capable of ilexing suilciently to conform to the head of a person and permit the hair waving clamps and protectors to be disposed in the desired arrangement on the head of a person.

Another object of the invention is to provide a protector adapted to present a curved surface to the head of a person to fit and conform to the configuration of the same and at the same time present a ilat upper surface for supporting the hair waving clamp and its heating element and adapted to afford the very desirable feature of allowing the hair waving clamp to be arranged a minimum distance from the head and thereby more effectively wave the hair.

It is also an object of the invention to provide an automatically opening protector adapted to be maintained closed when in position on the head of a person and capable when open .of affording access to its interior to facilitate the passing of strands of hair through the protector to the hair Waving clamp and enable the opening in the top of the protector for the passage of the hair to be securely sealed by tight packing of the hair so as to exclude steam'from the interior of the protector and prevent steam from seeping through the top opening of the protector and reaching the scalp of a person.

A further object of the invention is to provide a protector adapted to permit the hair waving clamps to be placed end to end as closely as desiredand capable of use in connection with any suitable air supplying means and of also furnishing adequate protection without a blower and provided with means for engaging the scalp cooling tubes of a blower to assist inholding said tubes in position on the head of a person.

Another object of the invention is to'provide a simple and efficient blower having a manifold adapted to supply air to a plurality of scalp cooling tubes and provided with means for enabling one or more unused tubes to be plugged to prevent the escape of air from such tubes.

With these and other objects in view, the invention consists inthe construction and novel combination and arrangement of parts hereinafter fully described, illustratedin the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportions and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of theinvention.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, the hair waving apparatus comprises hair waving clamps I designed to be arranged on the head of a person in groups or rows as illustrated in Figure 1 of the drawings and supported by hollow protectors 2 which are illustrated in detail in Fig. '7 of the drawings, and which are preferably supplied with' continuous currents of air by scalp cooling tubes 3 connected with a blower 4 by conecting tubes 5. The hair waving clamps, which may be positioned on the head of a person in any desired arrangement, are preferably disposed in transverse rows and Vinde-- pendently extend longitudinally of the head as shown, that is, the rows of hair waving clamps which are separated by the tubes 3 extend across the head from one side to the other while each individual hair waving clamp has its greater dimension extending longitudinally of the head at right angles to the direction in which the rows extend. The hair waving clamp which is of the ordinary Croquignole type comprises in its construction a pair of clamping bars E5 and 'I connected at one end by pivots 8 to a bearing bracket 9 and detachably connected at the other end by a locking device. The locking device consists of a cam lever Iii and spaced link plates I l arranged at the upper and lower faces of the adjacent ends of the clamping bars or members 6 and 'l and connected at one end to the clamping bar E by a pivot I2. The pivot I2 passes through the link plates at one end thereof and the cam lever i9 is fulcrumed between the other ends of the link plates by a pivot I3. The clamping bar 'I which is engaged by the locking device is provided at the outer side with a segmental recess Iii which receives the cam portion I5 of the cam lever ill when the clamping bars are locked in their closed position. The cam portion l5 extends from the cam lever approximately at right angles thereto, so that when the parts are locked, the cam lever extends along one side of the clamping bar 1. The clamping bars when locked are slightly spaced at their inner edges and are provided at their lower faces with combined insulating and clamping strips IS of rubber or other suitable material adapted to yieldab'ly clamp a strand or tress of hair and form a seal between the heating element, not shown, which, when the apparatus is in use, surrounds the curling rod I'I. The hair I8 is tightly wrapped around the curling rod I1, which is provided at its ends with trunnions I9 and 2t, the trunnion I9 being arranged in a bearing recess 2l of the bearing bracket and the trunnion 2D being arranged adjacent a bearing lug 22 carried by the upper link plate I I and located at one end of the curling rod adjacent the trunnion 20 when the parts are assembled. The extended trunnion I9 is provided with a suitable grip 23 for enabling it to be conveniently rotated for winding the hair tightly around the curling rod, and the latter is locked against retrograde rotation by a spring pawl 24 secured to the bearing bracket and engaging a ratchet wheel 25 formed integral with the curling rod. The curling rod is provided with the usual pivoted clamp 26 for clamping the hair to prevent the same from slipping while winding the hair on the curling rod.

The heating element preferably consists of an electric heater of the well-known type used in connection with the conventional type of Croquignole hair waving clamp. As the construction and arrangement of the heating element is well known, illustration thereof is deemed unnecessary.

The hair waving clamp protector, which is constructed of sheet metal or other suitable material to form a rigid structure, is substantially oblong and hollow, being composed of a flat top wall 21, spaced side walls 28, and a bottom wall composed of two spaced leaves or sections 25 and 3D which are slightly curved transversely to enable the protector to present a transverse concave lower face to conform to the configuration of the head of a person. The sections 29 and 3e of the bottom wall are formed integral with the side walls 28, and one of the side walls is integral with the top wall. The other side wall is hinged at 3i to the top wall, and the side of the protector formed by the bottom section 29 and the adjacent wall 28 is adapted to be opened automatically by a spring 32 when it is free to move. The spring 32, while having sufficient strength to open the hinged side automatically, is sufiiciently light to permit the hinged side 29 to be maintained closed when the protector is in position on the head of a person and the hair waving clamp is arranged upon the protector. The hinged leaf or section 29 when in its closed position as illustrated in Fig. 3 of the drawings abuts against the contiguous side edge of the top wall which forms a stop and enables the hinged section in its closed position to form a rigid support for that side of the protector. The top wall of the protector which presents a flat surface to the hair waving clamp is provided with a central, relatively narrow, longitudinal opening 33, and the inner adjacent edges of the sections 29 and 3D are spaced slightly from each other when the hinged side of the protector is closed.

A strand or tress of hair is adapted to be passed through the opening 33 in the top of the protector and to be pulled up perpendicular to the scalp. The hinged side affords access to the interior of the protector and facilitates more compacting of the hair in the opening 33 and the sealing of the top of the protector by the hair at the scalp side to prevent the possibility of steam escaping to the scalp along the hair strands. After the strand or tress of hair is passed through the opening 33 in the top of the protector and while the protector is spaced from the scalp, the hinged bottom section or leaf 29 is closed and the protector is moved downwardly on the strand or tress of hair and isftted against and placed in proper position on the scalp. The section or leaf 3l] which is formed integral with the contiguous side wall and the top wall of the protector cooperates with the side partition to form a rigid structure at that side of the-protector. The bottom sections 29 and 3U are provided with a heat insulating coating 34 of rubber or other suitable material, and a sheet 35 of felt or other suitable material is secured to the top wall of the protector exteriorly thereof and is provided with a slit 36 through which the hair passes from the protector to the hair waving clamp. The sheet 35 of felt is adapted to fit tightly against the hair which is pulled up through the central opening 33, and the said sheet 35 assists in sealing the protector at the topl thereof and in preventing the passage of steam to the interior of the protector. The side Walls 2S are provided centrally thereof with groups of holes 3l forming ports for the discharge of air from the protector into the spaces at the sides of the protector between the same and adjacent protectors for cooling the scalp at the sides of the protector.

The ends of the protector are open and the spaced top and bottom Walls of the protector project beyond the ends of the side walls and provide recesses 38 to receive the side portions of the scalp cooling tubes 3 which extend across the head E of a person between the rows of hair waving clamps and protectors, as clearly shown in Figure 1 of the drawings. The scalp cooling tubes which are substantially elliptical in cross section have their side portions arranged in the recesses 38 of the protectors and are provided at the protectors with nozzle or jet holes v39 forming ports for the discharge of air into the protectors. The scalp cooling tubes which are arranged at both ends of the protectors and discharge air into the protectors from each end thereof are designed to supply air for cooling the scalp directly beneath the hair waving clamps and also for cooling the scalp at the sides of the protector. The scalp cooling tubes supply continuous currents of air, and the protector which takes the place of ordinary felt usually employed in connection with hair waving clamps of the Croquignole type permits a flow of air around the hair strands beneath the clamp. It confines the flow of air around the hair strand and over the scalp directly beneath the protector and the heating device of the hair waving clamp andA at the saine time allows a substantial amount of air to pass out at the sides of the protector for'cooling the scalp between the protectors.

While the protector is illustrated in the drawings as provided with a hinged side to afford access to the interior of the protector to facilitate the passing of the hair through the protector and the sealing of the protector at the top thereof, it will, of course, be understood that the hinged connection may be omitted if desired and the protector may also be employed without scalp cooling tubes arranged to discharge air into the protector, as the protector will afford complete protection for the scalp beneath the clampsand the heating elements and permit air to circulate around the strands of hair. The hollow pro.- tectors 2 may be used in conjunction with any nozzle type blower which will circulate air through them, and it is not necessary that the fit between the scalp cooling tubes and the ends of the` protector be tight when a scalp cooling tube is arranged at each end of the protector,

as a ow of air through the protector will produce the desired effect and will circulate air around the strand of hair and will also furnish sufficient air to cool the scalp at the sides of the protector. The scalp cooling tubes may be provided at the spaces between the protectors with nozzle or'jetopenings 40 for the discharge of air into said spaces for cooling the scalp. As the upper walls of the protectors overlap the side portions of the scalp cooling tubes, the latter will be maintained in place on the head of a person when arranged between the ends of the adjacent rows or groups of protectors.

The scalp cooling tubes which are preferably constructed of metal are sufficiently exible to enable them to conform to the configuration of a head of a person and they are preferably insulated against the conduction of heat by a coating 40a of rubber or other suitable material and they are preferably provided with deflectors 4I for directing downwardly against the scalp the air discharged at the sides of the scalp cooling tubes. The deflectors 4| preferably consist of flaps and may be conveniently formed by a strip of rubber 42 or other suitable material secured to the scalp cooling tubes and extending longitudinally of the same and projecting at opposite sides thereof. The strips 42 may be secured to the tubes in any desired manner, and each tube has an inner reduced cylindrical terminal portion 43 which fits in cylindrical coupling portions 44 of the connecting tubes`5 of the blower 4. The outer ends 45 of the scalp cooling tubes are closed and are provided with laterally extending hooks 45 which are adapted to engage with the hair of a person to assist in maintaining the scalp cooling tubes in position and to prevent the same from being accidentally withdrawn from the head of a person. While the laterally extending hooks are shown at one side only of the closed ends of the scalp cooling tubes, they may, of course, be arranged at both sides of the same if desired.

Also, instead of arranging the scalp cooling tubes transversely of the head of a person as illustrated in Figure l of the drawings, they may be arranged longitudinally of the head with the tubes 3 extending from the back of the head to the front thereof instead of across the head from one side of the same to the other side thereof as heretofore explained. rThe blower 4, which is designed, in one use, to be secured to the back 41 of a chair, or it may be otherwise mounted, in a vertical or other position by a suitable clamp or bracket 48, consists of an electric motor 45, a motor actuated fan 5!) and a casing 5l receiving the motor and the fan and arranged in spaced relation with the same and provided at the top with an air distributing head or manifold 52 and having an air intake opening 53 at the lower end. A motor shaft 5&3 extends downwardly from the lower end of the motor which is of cylindrical form, and the fan consists of a conical shell secured-to the motor shaft 54 by a nut 55, asuitable spring locking Washer 55 being preferably interposed between the nut and the fan as clearly illustrated in Figure 14 ofthe drawings. The conical shell of the fan 5!! is provided at the apex with a hub portion 51 having a centralopening through which the motor shaft 5d passes. On its exterior, the conical shell of the fan 59 is provided with an annular series of fan blades 59 having a longitudinal inclination and a slight lateral inclination and tapered upwardly as shOWn.

The fan is provided at its apex portion with a circular recess 60 forming a seat for the spring locking washer 56. The upper edge of the conical shell of the body portion of the fan is arranged adjacent a circular band 6| approximately L- shaped in cross section and fitting the lower end of the motor 49 and secured to the same by bolts 52 or other suitable fastening devices; The band 6l which supports the motor and the fan within the blower casing is'provided with radial lugs 63 having threaded sockets 64 for the reception of screws 65 for securing the band to a central main section 66 of the casing 51 of the blower.

The casing 51 of the blower consists of the substantially cylindrical central section '66, a lower section B1 and the air distributing head or manifold 52 which constitutes a top section of the blower casing'. The main intermediate section 66 which is secured to the back of the chair has a tapered upper end 68 which terminates in a cylindrical flange or portion 69 into which the distributing head extends. The distributing head, which has a circular lower portion to iit the flange 69, is secured to the same by suitable fastening devices, and it is tapered upwardly to provide sloping sides and an approximately horizontal top portion 'lll which is provided with a series of air outlet openings 1I forming sockets for the reception of one end 12 of the connecting tubes, the other end of the connecting tubes being coupled to the scalp cooling tubes as heretofore explained. The connecting tubes 5 are detachably secured in the outlet openings of the air distributing head by clamping screws 13 which pierce the upper portion of the distributing head at one side thereof, as clearly illustrated in Figure 10 of the drawings. The distributing head is also provided at one side with a plurality of sockets T4 closed at the bottom and adapted to receive outer ends of one of more unused connecting tubes for plugging the same to prevent the escape of air therefrom. Any number of the sockets 'Hl may be provided and, while five of the air outlet openings 'II are shown in the air distributing head, any desired number may, of course, be provided to suit the capacity of the blower.

The lower section 61 of the blower casing, which is secured to the intermediate section by the fastening devices '55 of the motor supporting band, consists of a cylindrical upper portion and a tapered lower portion having the air intake 53. The lower section 61 is provided at the air intake 53 with a cylindrical ange or portion for the reception of a cap 75 for securing a suitable air ltering material 'l5 over the air intake for excluding dust and the like from the blower.

Leads l1 for supplying the motor of the blower with electric current extend through a hollow radial lug 18 formed integral with the attaching band 6I and extending from the band to the blower casing as clearly illustrated in Figure 9 of the drawings.
